I fell down before the Lord, as at the first - Moses interceded for the people before he came down from the mountain the first time Exodus 32:11-13. This intercession is only briefly alluded to in this verse. Afterward he spent another 40 days on the mountain in fasting and prayer to obtain a complete restitution of the covenant Exodus 34:28. It is this second forty days, and the intercession of Moses made therein (compare Exodus 34:9), that is more particularly brought forward here and in Deuteronomy 9:25-29.

And I fell down before the Lord,.... In prayer for Israel who had sinned; but this he did not immediately after he had broken the tables, but when he had first ground the calf to powder, strewed it on the water, and made the children of Israel drink it; and when he had chided Aaron, and ordered the sons of Levi to slay every man his brother:

as at the first forty days and forty mights; which is to be connected, I think, not with what goes before; for we read not that he fell down before the Lord, at the first time he was with him so long in the mount; but with what follows: "I did neither eat bread nor drink water"; as he neither ate nor drank the first forty days, so neither did he these second forty; see Deuteronomy 9:9.

because of all your sins which ye sinned, in doing wickedly in the sight of the Lord, to provoke him to anger; for they were guilty of more sins than one; besides idolatry, they were guilty of unbelief, ingratitude, &c. which were notorious and flagrant, were done openly and publicly, in sight of his glory and majesty on the mount; all which must be very provoking to him, and on account of these Moses prayed and fasted.

And I fell down before the LORD, as at the first, forty days and forty nights: I did neither eat bread, nor drink water, because of all your sins which ye sinned, in doing wickedly in the sight of the LORD, to provoke him to anger.

9:18 I fell down - In a way of humiliation and supplication, on your behalf.

18. I fell down before the Lord-The sudden and painful reaction which this scene of pagan revelry produced on the mind of the pious and patriotic leader can be more easily imagined than described. Great and public sins call for seasons of extraordinary humiliation, and in his deep affliction for the awful apostasy, he seems to have held a miraculous fast as long as before.

9:7-29 That the Israelites might have no pretence to think that God brought them to Canaan for their righteousness, Moses shows what a miracle of mercy it was, that they had not been destroyed in the wilderness. It is good for us often to remember against ourselves, with sorrow and shame, our former sins; that we may see how much we are indebted to free grace, and may humbly own that we never merited any thing but wrath and the curse at God's hand. For so strong is our propensity to pride, that it will creep in under one pretence or another. We are ready to fancy that our righteousness has got for us the special favour of the Lord, though in reality our wickedness is more plain than our weakness. But when the secret history of every man's life shall be brought forth at the day of judgment, all the world will be proved guilty before God. At present, One pleads for us before the mercy-seat, who not only fasted, but died upon the cross for our sins; through whom we may approach, though self-condemned sinners, and beseech for undeserved mercy and for eternal life, as the gift of God in Him. Let us refer all the victory, all the glory, and all the praise, to Him who alone bringeth salvation.
